IMPROVEMENT IN MARBLEIZING PAPER AND OTHER FABRICS.

Specification forming part of Letters Patent NQLQMJGG, dated May 48, 1878; application tiled April 8, '1878. i

To all whom it may concern: Be it known that I, GEOBG Gnossnnm, of Elberfeld, Prussia, Germany, have invented. an Improved Process of Marbleizing Paper and other'fiubstances, of which the following is a specification: Figure 1 is a vertical'section of 'a 'marble block prepared according to my invention. Fig. 2 is a face view of a piece of paper printed according to the invention.

Similar letters of reicrence indicate corresponding parts in all thefigures.

The object of this invention is to transfer to paper or other substance 21- correct representation of the veins of any suitable-kind of marble.

The invention consists in sinking the veins into the surface of a polished slab or block of marble, and tlieuprintin g with the marble thus prepared. 7

After the maiblehas been cut into flat slabs or cylindrical blocks, according to the style of press wherein it is to be used, it is properly smoothed or polished, and its natural veins are. thereupon either etched chemically or cut to a certain depth by engravers tools, so that the veins will be sunk below the printing-surface of the sla-b or block. The block or slab V isnext inserted in a suitable printing-press and supplied with printing colors, so that impressions may be taken therefrom upon paper or other fabric.

The marble A thus' prepared, and havin g its natural veins sunk below the polished surface,

as at a. a in Fig. 1, may also be used for making electrotypes or stereotypes therefrom. 1

In printing from the marble block or slab,

the coloring matter is eitherapplied to the projecting polished surface, as in. ordinary type-printing, or to the receding eins, as in lithographic printing.

I claim- The process of reproducing'the natural veins of marble on paper or other fabric by sinking the natural veins of a block or slab of marble below the polished surface thereof, and thenprinting from the surface thus produced, or

from a metallic reproduction thereof, substantially as specified.

This specification signed by me this the 9th day of March, 1878.

GEORG GROSSHEIM.
